Abstract
Introduction: Due to modernized lifestyle large number of population are becoming obese and suffering from respiratory and cardiovascular disorders too. The population with asthma is increasing globally. Spirometry is a traditional method used to assess asthma and severity. Several studies have reported that asthmatic patients have developed arterial hypertension and there is some relationship between these two diseases along with BMI. But still few controversies existed.
Aim: The aim of this study was to evaluate the correlation between Body Mass Index (BMI), Mean Arterial Blood Pressure (MABP), and Spirometric parameter Peak Expiratory Flow Rate (PEFR) in Patients of Asthma.
Material and Method: This is a cross-sectional study conducted in Physiology department, in collaboration with the TB and Chest Diseases department of Jawaharlal Nehru Medical College, JNMC, AMU, Aligarh from 26th January, 2024 to 26th January, 2025. Forty Asthmatic individuals, aged between 18–40 years were recruited in the study and have been evaluated for weight, height, Arterial blood pressure, and PEFR (spirometric parameter). The reason for choosing PEFR is that it’s a reliable representative for functioning of airways. Correlation test have been performed to find the correlation between body mass index and peak expiratory flow rate, and mean arterial blood pressure.
Result: R-value obtained was 0.138 (r = 0138) and has been observed between PEFR and BMI which revealed a weak negative correlation, revealing that as BMI increases PEFR is decreased. Between MAP and PEFR a linear correlation is revealed.
Conclusion: This Study has confirmed a strong association between PEFR & MAP, and a weak association between BMI & PEFR in Asthmatic individuals.
